3 Things To Look Out For During The State Of The Union

President Trump will address Congress for the second time tonight.

President Donald Trump is set to deliver his State of the Union address at 9 p.m. on Tuesday, the second of his presidency. Here's what experts are saying you should watch out for during the address:

1) President Trump will reportedly call to end HIV transmission by 2030, according to The New York Times. A senior administration official told the Times that government scientists have been working on a plan that will call for increased use of medicines that lowers the chances high-risk people become infected.

2) And call for unity during a time of polarization. In 2017, the president made similar comments. "I am here tonight to deliver a message of unity and strength," he said in February of 2017. "And it is a message deeply delivered from my heart." Critics pointed out that while he may call for unity, Trump spent the morning tweeting criticisms and attacks at Democratic Senate Minority leader Chuck Schumer.

3) He will make a case for the border wall. Fresh off the longest government shutdown in U.S. history, it's safe to bet the president will once again make a case for why the United States needs a wall on its southern border. Despite being one of his most controversial policy initiatives, the border wall was a signature promise during the president's campaign and he continues to make the case that it will make America safer. With talks at a standstill in Congress, expect Trump to amp up the pressure and the rhetoric to push construction of the wall forward.

There won't just be action happening at the podium, either. Democratic Rep. Nancy Pelosi will be seated behind President Trump, returning to her position as Speaker of the House of Representatives for the first time during his tenure as president. Several politicians will also be bringing guests to the event, per Congressional tradition. Freshman Democratic Rep. Alexandria Ocasio-Cortez is bringing the activist who confronted Jeff Flake in an elevator, a woman who happens to live in her district. Pelosi is bringing chef José Andrés, who has helped feed victims of Hurricane Maria in Puerto Rico and — more recently — furloughed federal workers. Republican Sen. John Kennedy is bringing Justina Pettaway, a custodian in the U.S. Capitol building, as a thank you for her work.

You can tune into the State of the Union address at 9 p.m. Eastern Standard Time on most cable news channels.
